9 Claims.

My invention relates to braiding machines and particularly to devicesfor actuating stopping mechanism therefor in the event of breaking of athread guided to the braiding point for incorporation in the braid.

Heretofore, it has been customary to provide each travellingthread-carrier of a braiding machine with a stop actuating device, suchas a thread supported slide, for causing stopping of l the braidingmachine on breakage of the related braiding thread.

In cases where a core, such as an elastic thread, is incorporated in thebraid it has also been customary to provide each carrier with anadditional stop actuating device, such as a slidable and/or rotatablehub, each carrier supported hub being operative on breaking of any corethread to cause stopping of the machine. The provision of two devices oneach carrier for actuating the stopping mechanism obviously adds to thecomplexity of the machine and increases the cost of equipping it forautomatic stopping on breakage either of any braiding thread or any corethread.

A feature of my invention is the provision of a single stoppingmechanism actuating device on each carrier.

A second feature is the provision of a single stop mechanism actuator oneach carrier which is responsive to breaking of the related braidingthread and also to breaking of any core thread for causing stopping ofthe machine.

In carrying out my invention I provide each carrier with a standardserving as a guide for a thread supported slide. The actuator for theoperating lever of the stopping mechanism is mounted on the standard asa separate slidable member and is connected to the thread supportedslide by a releasable connecting member. The connecting member ispivotally mounted on the stop actuator and normally engages the threadsupported slide so that both are suspended from the braiding thread. Theconnecting member has portions adapted to contact a projecting portionof a member normally supported by a core thread so as to be operated fordisconnecting the stop actuator from the braiding thread supported slideto permit the actuator to independently drop into position for causingstopping of the machine on breakage of a core thread.

In the drawings Figure 1 is a front elevation, partly in section, ofpart of a braiding machine and shows a travelling thread-carrierprovided with a device for actuating stopping mechanism on breakage of acore thread or a braiding thread;

Figure 2 is a side elevation, partly broken away, of a carrier showingthe stop actuator thereof positioned to cause stopping of the braidingmachine as a result of breakage of a core thread;

Figure 3 is a side elevation and shows my stop actuating devicepositioned to cause stopping of the braiding machine as a result ofbreakage of a braiding thread;

Figure 4 is a view on the line 4-4 of Fig. 1, and shows the stopmechanism actuator about to be disconnected from the slide suspendedfrom the braiding thread for causing stopping of the machine as a resultof breaking of a core thread; and

Figure 5 is a sectional view on the line 5-5 of Fig. 2 and shows therelation of the stop actuator to an operating lever for the stoppingmechanism.

Referring to the drawings, the numeral 10 designates one of the numeroustravelling threadcarriers provided in a braiding machine. Carrier 10 hasa base comprising plates 11 and 12 spaced by a member 13 whichcooperates with the usual sinuous grooves 14 in the machine bed 15 forguiding the carrier in its braiding movement. A spindle 16 extends fromplate 11 and supports a spool 17 from which a braiding thread 18 extendsthrough thread guides 20, 21, 22 and 23 to the braiding point.

The thread guides 20 and 22 are mounted on 35 a standard 24 carried byplate 11 and the guide 21 is formed in a slide member 25 guided onstandard 24 and normally supported in raised position thereon by thread18 extending between guides 20 and 22 through guide 21. Member 25 inturn supports a stop actuating member 26, also slidably mounted onstandard 24, through the engagement of the hook portion 27 of areleasable connecting member 28 carried by member 26 with lugs or otherprojections 30 on member 25.

Stop member 26 has wings 31 projecting beyond the sides of standard 24and spindle 16 and adapted to be positioned in the plane of a lever 32for engaging and actuating the latter as carrier 10 in traversing groove14 passes the point at which the lever is mounted on bed 15.

Lever 32 on actuation by member 26 is adapted to operate any desirableform of stop mechanism such as is usually provided for stopping braidingmachines. As shown lever 32 is fixed to a stub shaft 33 journaled in bedplate 15 and is operatively connected through members 34, 35, etc. toset the stop mechanism in operation. It is to be understood that anumber of levers 32 are provided at various points on bed plate 15, as

usual, in order to avoid undue delay in stopping the braiding machine.

A standard 36 fixed on bed 15 between sinuous grooves 14 supports apulley 37 which guides an elastic thread 38, or other core to beincorporated in the braid, from a suitably located'supply source to thebraiding point. Standard 36 has a bracket 40 and a hollow base portion41 which form guides for a member 42 having a loop43. by which it issuspended from thread 38. Member 42 is formed with a projection 44-adapted to be dropped into the path of the membrane moving with carrier10. On breakage of core thread 38 the projection 44 engages z'md opcrates member 28, as a carrier passes the'poirit at which a core threadhas broken, to disconnect stop actuating member 26' from member 25-through which it is suspended from=braiding-.

thread 18 so that member 26 becomes positioned for engaging andoperating a-lever:32 tosstop the braiding machine.

Referring particularly to Figures 1;;4 and 5, member 28 comprises anirregularly but symmetrically bent wire formed with looped portions 45by which it is pivotally mounted on stop member 26. The wire member 28is bent-t0 provide the hook portion 27 for's'upporting member 26'01-1member 25 and also to provide portions 46 extending at each side ofspindle 15 and standard 24 for engagement withithe projecting portion 44of the core thread supporting member 42. It will be apparent that a stopmember 26 functions to cause stopping of the braidingmachine on breakageofeither a braiding thread 18 or a core thread 38. On breakage of abraiding thread l8'the members 25 and26 are no longer supported therebyand both move-downwardly on standard 24 to position member'26 foractuating stop lever 32, as indicated in Figure 3. On

breakage of a core thread 38 the member 42 is no longer supported andbecomes positioned, as indicated inFigures 1 and 4, by aportion 46 ofconnecting member 28 to pivotallymove the latter and thus disconnectstop member 26 from member 25 through which it is suspended frombraiding thread l8. Stop member 26 then falls to position for actuatingstoplever 32 as indicated in Figure 2.

Afterstopping of the braiding machine as aresult of breaking of 'abraiding thread,the thread '18 is again passed through the guides 20,21, 22'to "support the stop actuating member 26 and slide 25. Intheevent stopping results from breakage of a core thread 38, the slide stopactuating member 26 is moved upwardlyon standard and again connected toslide member 25 by the connecting member 27, 28.
